I had the privelege of creating this graffe rig for a Disney Research augmented reality project that utilized the Unity engine. Because the rig needed to work in Unity, I had to make some specific features for our pipeline to ensure the rig performed adequently. While there were some restrictions, I dedicated as much time as I could to make the rig as robust as possible for animation. This includes a number of FK/IK hybrid sytems, an array of custom foot controls for locomotion, and a fully functioning facial rig. I also created a version of this rig that featurs squash and stretch functionality for the limbs, while preserving the volume of the geometry.
In particular, I spent a good deal of effort on the giraffe's most dominant feature - the neck. In addition to having both FK and IK controls active simulataneously, the neck contains a number of math utility nodes to allow for mesh volume preservation. Since this character's primary movement for the project was to walk, I also made sure to include a wide number of foot features to achieve locomotion. Some of these include a three-pose rolling motion, banking, fetlock compression, and pivoting.
